A buddy got a PTW the other day, and phoned me all in a panic when he saw a BB shatter on him. I let him try one of my mags with Metal Tech BBs, and the gun ran fine, no breaks. His mags were filthy with dirt, sand, grass, etc.

Once we cleaned one of his mags out, and tried his BBs, breaks were fewer, but still occuring. He was using Madbull 0.25g BBs, and when we tried the Metal Tech in his mag, it ran fine the whole mag.

So, I decided to do a crush test on the Madbull BBs. When I crushed it to an easy stop with the pliers, the Madbull split in 3 or 4 areas, and the BB was deformed to 4.02 mm. The Metal Tech when tested split once only, but deformed to only 5.10 mm. The Madbull made a little "POP" sound when crushed, while the Metal Tech was virtually silent.

I would not recommend Madbull for a PTW, or any other gun with a steel nozzle or chamber.
